The New Nova Delphini 2013 on August 16th, 03:13ut. Discovered by a Japanese amateur astronomer Koichi Itagaki of Yamagata, Japan two days ago at a magnitude 6.2 then and now much brighter from my observation the day before, estimated now between 4.5-6 magnitudes (outburst?). It is located in the constellation Delphinus. (Equipment: LX200ACF 12 in. OTA, F6.3, CGE mount, ST402me NAB Ccd, Astronomik LRGB filter set.)

I've put a nice comparison together using the images from the Digitized sky survey of 1990 and my image of 16th of August. It clearly shows the brightness of the nova and on the Digitized Sky Survey image you can see the progenitor...

The attached image shows the evolution of the spectrum of Nova Delphini over 2 1/2 weeks.
Taken from my backyard in Berkeley CA., dodging clouds and fog on the first two nights, but as clear as it ever gets in Berkeley for the rest. Taken with a modified Canon T1i (filters removed) Celestron C8 with Rainbow Optics diffraction grating between the scope and the camera.
Scope positioned and allowed to drift for 4 sec with the shutter open at iso 6400. All spectra are identical exposure time and ISO.
Fascinating to imagine what is going on at the nova to cause the continuum to fade while the hydrogen emission lines remain so strong. Reminds me of the spectrum of "Campbells Hydrogen Star" - a planetary nebula with a red shell and almost no Oiii emission but relatively strong Hbeta.
The zero order thru the grating gives an indication of the overall fading of the nova.
